MONORAIL SYSTEM.

Application filed March 20, 1925.

This invention relates to improvements in railway systems, particularly of the monorail type, and it is the principal object of my invention to provide a monorail road ensuring the utmost safety of travel and allowing the transportation of a considerable number of passengers in a limited number of cars.

Another object of the invention is the provision of a monorail railway system including devices for safely guiding the cars around curves, and one which can be operated by electric, steam or any other source of power.

A further object of the invention is the provision of a monorail railway system using cars of the double-deck type and including novel means for coupling two cars together, the superposed cars as well as the adjoining cars on the same level.

A still further object of the invention is the provision of a monorail railway system having novel and improved means for switching the cars from one railto another and for braking the cars quickly and effectively to hold them instantaneously.

These and other objects and advantages of my novel railway system will become more fully known as the description thereof proceeds, and will then be specifically pointed out in the appended claims.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a perspective view of a monorail railway system constructed according tothe invention, showing two cars of the system traveling in opposite directions.

Fig. 2 is a longitudinal vertical section. through one car of the system.

Fig. 3 is a cross-section through one of the cars along line 3-3 of Fig. 2.

Fig. 4 is an elevation of a car of a moditied type.

Fig. 5 is a sectional detailed view of the buffer arrangement.

Fig. 6 is a detail sectional side elevation of a swivel wheel used for safely guiding a car on its rail around curves, etc.

The tracks 10 of the improved monorail railway system according to the invention have substantial triangular cross-sections Serial No. 16,935.

and are supported on posts 11 of any suitable material and height, set at suitable intervals along the right of way of the road. Parallel to and at a certain distance beneath the monorail 10, a guard rail 12 is carried by the posts 11 for a purpose hereafter more fully to be described.

The cars used with the system are preferably of the double deck type, the upper section 13 and the lower section letare both equipped with a plurality of seats 15 of the customary type, windows 16 and entrance and exit doors 17 and 18 arranged in any suitable and required number either in the center or at the ends of a car allowing simultancous leaving and boarding of passengers on the elevated superposed platforms.

The lower section has end vestibules for the operator controllers, etc, and at the center the car ends are formed like chambers 19, the walls of which form the bean ings for shafts 20 of wheels 21 of the pulley type running on top of the rails 10.

Other chambers 22 and 28 are located at both sides of chamber 19 and are equipped with platforms 24 and 25 respectively in which bearings are formed for the vertically rranged stubshafts 26 and 27, carrying upper guide roller blocks 28 on top of platforms 24.- and 25, and extending through slots 29 in platforms 24: and 25. The lower ends of the shafts 26 and 27 are journaled in the bottom part of lower section 14 and carry above the same rollers 30 and 31 adapted to engage the guide rails 12 from opposite sides.

The guide roller blocks 28 carry each at its outer face, a rod 32, to which a piston 33 is attached working in a horizontally disposed cylinder 34 against the action of a spring 35 within the cylinder. The outer end of the spring is secured to a plate 36 within the cylinder to which a. pin 37 is attached, extending through the end wall of the cylinder and being threaded, carries an adjusting nut 38 or the like permitting the regulation of the spring tension within certain limits. A similar arrangement is made at the lower end of shafts 26 and 27 between and below car bottoms. In order to allow passengers to pass from the upper arranged in with my improved monorail system to the lower section of the car, the stairs 39 and 40 are provided located in approximately the middle of each car.

In order to guide the wheels 21 safely around the curves in the track 10, the wheels 21 and their housingsare constructed to swivel around vertical pins ll passed through the wheel housing at their upper and lower ends, while their middleparts extend through a boss 42 formed in the car frame.

The connection between each two cars must also be such as to allow a safe rounding'of the curves, and for this purpose the ends of the cars overlap in the manner in dicated in Fig. 2 at a3 and carry at their extreme outer ends bellows t l or the like to effect a tight closure. In order to facilitate any relative movement of the two adjoining cars, aplurality of rollers 45 are the space between the tops of the two cars, while strong soiralsprings 46 take care of, or absorb any s ocks developed during the turning movement when taking a curve.

The cars are equipped with the customary signal lights 4:7: near their tops and may be ventilated andlighted in any suitable well-known manner.

In Fig. 4 a'modifica-tion of a car used is shown, 6211 4-.8, of which has a chamber 49 formed therewith at its center, the walls of which carry a shaft 50 for the pulley roller or wheel 51 in the groove of which engages the apex of the triangular rail 52 supported on posts which supportalso aguide rail 54 at, a distance underneath rail 52 and parallel thereto.

To the bottom of the car 48 the frames 55 and 56 are attached at opposite sides of the rail 52 and carry at their lower parts platforms 57 and 58 respectively. These plat-forms have journaled therein vertically arranged shafts 59 and 60 respectively which carryat their upperends the guide rolls or blocks (51 and ("32 constructed as in the preferred form to work-with their rods in spring cylinder in the same manner as described with my preferred form.

"Between the platforms 5'? and .58 the shafts E59 and 60 carry rollersGS and 'G l adapted to engage the guide-rail oet'froni opposite sides, while their lower ends carry a pair of rollers or blocks, similar to the blocks '61 and 62 and cushioned in the same and by using only one elevated rail, will prevent danger of crossings.

Yet the construction of my system is so simple that lots of material could be saved for its support and in case of towns where it might be used, will free the streets from much structure, giving more light, air and sight.

The construction of one track and pillars instead of dirt, cut stones and cut sections of wood transverse and other material .now used,w ill be more economical and by its solid base (which may be concrete) can be placed anywhere, even in thequnleveledground, sand or mud.

YVood. beams reinforced it necessary with ;T metal bars or metal. tubings, concrete or any other strong building material, can. be used for thesupporting of the metal rail.

A suitable number of doors 70, are provided in the bottom of the lower platform of the carthrough which suitable ladders may be lowered for the passengers to ,de-

scend in case of emergency.

It. is to be understood that such changes may be made in the general arrangement or the construction of the minor. details of my system 'asfallwithin the scope of the appended claims, without departure from the spirit of the invention.
